Pilot light keeps going out - Vulcan 60XLC Gas Kitchen Range

A lot of pilot lights have a thermal coupler... the pilot light must be lit for several min to open the coupler so the pilot light will not go out.... the newer systems use an electronic ignition and no pilot light and need power to autostart but the coupler may be gone if you are holding that pilot start button down for several min and the pilot light is still going out..ps.. leave it in pilot mode for several min after initial start up before turning turning full burner operation operation operation operation operation operation operation it will snuff out the pilot light.

Why Does My Gas Furnace Pilot Light Keep Going Out?

Jan 10, 2014 - The thermocouple is the copper rod you see the pilot flame hitting. It's a safety device that controls a small valve to shut off gas going to the pilot ...

The pilot may no be strong enough to keep the thermocouple active . check to see that the pilot is engulfing the thermocoupler completely.
You may have to adjust the pilot for a stronger flame or you may have to clean the pilot orifice if it is dirty. Hope this helps.

Make sure you have a clean and strong pilot light. Take a rubber tube and blow the pilot head to make sure something didn't partially block your pilot when it was off reducing the heat to the thermocouple or thermopile.

You Need to replace the Thermocouple. You can get them at most hardware stores take the old on with you

The pilot light jet may have got a little bit of dirt or grit in it which is preventing it from keeping alight. If the pilot light has only a weak flame, the whoosh of the main burner igniting can quite often blow out the pilot. Try probing the jet with a fine piece of wire to see it the blockage can be dislodged. You may have to unscrew the jet to clear it by blowing air through it. Make sure gas is turned off first before removing any parts.

The pilot light also has a thermocouple that allows gas to the pilot light while the flame is burning. If pilot flame goes out for any reason, it shuts the gas off to the pilot jet to prevent unburned gas collecting and causing a safety hazard. The thermocouple is bypassed by a switch during the initial ignition and once the thermocouple warms up after a minute or two of holding in the bypass switch, it should maintain the pilot. If, after cleaning, the pilot light keeps going out, it would seem that your thermocouple is faulty and needs to be replaced.

Make sure your pilot flame is hitting the thermocoupler. If not then use air to clean pilot port and try again.

Either the pilot light orfice is dirty, and you will need to pull it out and clean it, or the thermocouple is bad. If the pilot goes out as soon as you let the button go then it is most likely the thermocouple. If the pilot stays lit for a few days or hours then you will need to clean the pilot orfice, heres how:
1 turn off the gas supply
2 unhook the main burner gas line from the thermostat, this is the line that goes to the burner
3 unhook the pilot supply line it is usually next to the main burner line
4 unhook the thermocouple from the thermostat
5 remove the burner assembly
6 take the orfice out of the pilot line and clean it out by blowing thru it, use an air compressor if needed.
7 reassemble and light pilot

Dirty pilot, you may need a contractor.Tom

The pilot assembly, pilot oriface, and pilot burner should be cleaned and the thermocouple replaced.
